Roller press plays a vital role in the production and processing of roof panels and wall panels. Its working principle is based on the mechanism of high pressure material layer crushing, through two relatively slow rotating rollers with equal speed to implement pure pressure on the material, so as to achieve crushing and shaping effect.
Specifically, the working process of the roller press includes material feeding, high-pressure compression, crushing, and discharge. During the feeding stage, materials are continuously fed into the roller press to ensure they enter the gap between rollers steadily and continuously, forming a relatively dense layer. Subsequently, the hydraulic system provides pressure to the moving rollers, creating a very high pressure between the two rollers, typically ranging from 50 to 300 MPa. This high-pressure environment causes the material particles to be crushed and micro-cracked between the rollers, achieving efficient crushing.
After being compressed by the roller press, the particle size of the material rapidly decreases, and there are numerous cracks on its surface, significantly improving grindability. This change greatly reduces the grinding energy required when the material enters the next process, thereby enhancing production efficiency and product quality. Ultimately, the material is discharged from the machine in the form of a dense cake, which can then be processed to obtain the desired roof or wall panels.
To sum up, the working principle of the roof panel and wall panel roller press is to crush and shape the material through high-pressure squeezing, so as to meet production needs. Its high efficiency and energy saving features make the roller press widely used in the field of building materials processing, providing strong support for the production of roof panels and wall panels.
